Weekend snow coming up? It's possible...

Low pressure developing in the southern branch of the jet stream this weekend will bring rain and thunderstorms through the southern Plains and Gulf, but could also provide a little snowfall for us this weekend.  It won't be much, about an inch or two, but temperatures will take a tumble Sunday afternoon behind that second cold front.

As it looks now, Saturday should start off dry but clouds will be on the increase through the afternoon.  Light snow, possibly mixing with rain, will start in Iowa and southwest Wisconsin between 3pm and 5pm.  As an upper level disturbance passes to the southwest of Rockford, snow will develop along a cold front and continue to slide southeast.

If you're headed out to the St. Patrick's Day parade in Rockford you should be okay, just bring a jacket.  Temperatures will be in the middle and upper 30's.  Expect snow to move into northern Illinois after 5pm.
